An Alabama Teenager Got ‘Fed Up’ With His Family Fighting. So He Killed His Parents and Three Siblings.

A teenager in Alabama was “fed up” with his family, so he killed his parents and three siblings and now he will spend the rest of his life behind bars, according to authorities.

On Sept. 7, Limestone County Circuit Judge Chad Wise, who said the crime was “ghastly, disturbing and draped in unmitigated evil,” handed down the sentence of life without parole for 18-year-old Mason Sisk, according to the Associated Press.

In April 2023, Sisk was convicted on four counts of capital murder in connection with the shooting deaths of his father John Sisk, 38; mother Mary Sisk, 35; and siblings Kane, 6, Rorrie, 4, and Colson, 6 months, on Sept. 2, 2019, in Elkmont when he was 14 years old, as Front Page Detectives previously reported.

In a written statement to the media, Limestone County District Attorney Brian C.T. Jones wrote, “I’ve prosecuted a lot of people in my career. And I can tell you that out of all of those people, only four out of five people scare the hell out of me and he’s at the top of my list,” WHNT reported.

Jones added, “Mason Sisk is clearly one of the most dangerous people who will ever be sentenced in Limestone County. With this sentence today, Judge Wise has ensured that Mason Sisk will NEVER threaten another child’s safety and wellbeing.”

Sisk did not offer remarks prior to his sentencing and since he was 14 years old at the time he committed the murders, he was not eligible for the death penalty, officials said.

Family members of the deceased gave victims’ impact statements in July, per WHNT. Douglas Prater, the brother of Mary Sisk, said, "A whole family has been lost. I lost my sister Mary. She loved you, and you killed her.”

Mary Sisk’s sister Katie said, "I do not know if I will ever forgive you, but I do grieve the loss of you. The child Mason that I knew died the day you murdered them.”

At the time of Sisk’s conviction, his attorney told WAFF they were “confident we're solid on the ground for appeal. It just feels like this inevitably will have to be tried again."

No appeal has been filed at this time, officials said.
